| Abstract(in English) | A single-chip architecture for three-dimensional(3-D)computer graphics(CG)is discussed assuming portable equipment with a 3-D CG interface.An on-chip DRAM cell array for two 3-D frame buffers and one 2-D frame buffer,the on-chip pixel generator,the on-chip frame synthesizer,parallel alpha-blending and Z-comparison circuits attached to the DRAM cell array are proposed.Estimation of the chip performance,assuming the 0.35-μm CMOS design rule and a volta ge of 3.3 V,shows that the chip size,power dissipation,the drawing speed,and the memory data I, O rate would be 14 x 13.5 mm,590 mw,0. 25 milhon polygons/s,and 1 gigabyte/s,respectively.Based on circuit simulations,the chip can run on a 1.5-V dry cell.A scaled- down version of the chip is being fabricated for evaluation. |
